n the Solar System," they'd called him. Fine stuff, that.
Stanton wondered what the asteroids were like. What would it be like to
live out in space, where a man still had plenty of space to move around
in and could fashion his life to suit himself? Maybe there would be a
place in the asteroids for a hopped-up superman.

Or maybe there would only be a place here, beneath the streets of
Government City, for a dead superman.

_Not if I can help it_, Stanton thought with a grim smile.

The walking seemed to take forever in one way, but, in another way,
Stanton didn't mind it. He had a lot to think over. Seeing his brother's
image on the TV had been unnerving yesterday, but today he felt as
though everything had been all right all along.

His memory was still a long way from being complete, and it probably
always would be, he thought. He could still scarcely recall any real
memories of a boy named Martin Stanton, but--and he smiled a little at
the thought--he knew more about him than his brother did, even so.

It made very little difference now. That Martin Stanton was gone. In
effect, he had been demolished--what little there had been of him--and a
new structure had been built on the old foundation.

And yet, it was highly probable that the new structure was very like
that that would have developed naturally if the accident so early in
Martin Stanton's life had never occurred.

Stanton kept walking. There was a timeless feeling about his march
through the depths of the ground, as though every step through the
blackness was exactly like every other step, and it was only the same
step over and over again.

He skirted a pile of rubble on his right. There had been a station here,
once; the street above had caved in and filled it with brick, concrete,
cobblestones, and steel scrap, and then it had been sealed over when
Government City was built.

A part of one wall was still unbroken, though. A sign built of tile said
125TH STREET, he knew, although it was hard to make it out in the dim
glow. He kept on walking, ignoring the rats that scampered over the
rubble.

A mile or so farther on, he whispered: "Barbell to Barhop. How's
everything going?"

"Barhop to Barbell," came the answer. "No sign of any activity from
Target. So far, none of the alarms have been triggered."

"What's he doing?" Stanton whispered. It seemed only right to keep his
voice low, although he was fairly certain that his voice would not carry
to
